To ALL To wHoM 41r MAY coNcnRN: i

Be it known that I, GEORGE ALLIX, of St. I-Icliers, Jersey, one of theislands in the British Channel, shipfl wright, have invented ordiscovered certain Improvements in Apparatus for Raising and LoweringWindow- Blinds, Windows, Maps, and other Articles, andv retaining them'in any required positiong and. I do hereby declare that the following isa true and exact description thereof, referencebeing hadto theaccompanying drawings and Vto the figures and letters marked thereon;that is to say,

My invention relates to theuse of chain in raising andloweringwindow-blinds mounted on rollers, and consists mainly-in theconstruction and employment, as hereafter described, in combination witha chainA of ya I slitor cut, into which the chain enters when left toitself, so that the chain is held in the slitA and the blind- -rollerprevented rotating; also in the combination, with the slit or cut, ofother parts, as hereafter described.

In carrying out this invention, I secure to the lower part of the sideof the window-frame a-bracket-or cleat, the upper portion of whichcarries a pulley, while in the lower portion a slit -or cut is made tocatch or nip the chain. A

vFigures 1 and 2 represent such a bracket in front and side views.

a is the bracket, I; thepulley, and e the slit or cut-l Fig. 1 shows a.window-blind with thel bracket applied to the window-frame. The upperend of the chain d is secured to a pin, e, en the end oi' theblind-rollerj', and is led down through an eye, g, and through thepulley b of the bracket or cleat. The circumference of the pulley b is,say, halt` an inch nearer the-'windowframetban the slit c. .-To raisethe blind, take hold of a ring or handle, it, on the lower end ofthechain, keep it out from the window-frame, andhaul on it, keepingthechain always taut, and when desired to stop the blind, let go the chainsuddenly or close it towards the frame, and one oi' the links will becaught in the slit c. To lower the blind, pullout the handle It,asbeforc, let the chain run, but keeping itwalways taut, and whenrequired to stop the bind let the chain catch in the slit as before.Sometimes I fit to the bracket a a lever, t',

pivoted to the bracket behind the pulley b, as seen in Figure 3, bylifting which on its pivot intothe position shown in dotted lines, thechain d is moved out of the slit c, and the blind runs down of its ownweight until the lever is released.

Another arrangement consists of a plate, a, as seen in Figure 4, securedto the window-frame, having a double lug, k, at the upper part, and adouble lug, Z, at the lower part.. Each lug has a pulley, e, fittedinit, but the lower lug l is, say, halt` an inch longer than the upper,and has a slit or cut, c, to catch the chain,'as before explained. i

Another arrangement consists of a plate, a, Figure 5, secured to thewindow-frame, and having two eyes,

lmet, one above the other-at its upper part. The upper eye m is plain,and takes the place of the pulley before described, and it-is as closeas possible `to the frame. The lower eye n is, say, half an inch fromthe frame, and is formed with a slit or cut, c, to catch the chain.

Another arrangement4 consists of a screw eye-boltyshown at a in planview in Figure 6, screwed into the window-frame, and having a shoulder,o, as short as possible. The eye is formed with u cut or slit, c, whichis in this case at the part of the eye'farthest from the frame, andtherefore thei chain d must be held towards the I frame instead of fromit in raising or lowering the window-blind or, if theeye-bolt be ofsulicient length, as

shown in Figure 7, the slit or cut Vc may be at the part Vof the eyenearest the frame. The pin e on the end of the blind-rollerf may be madeto turn in a bracket, p, as seen infg'. 1, carried out from a plate,screwed to the window-frameor in an ordinary side bracket, and thebracket in either casehas an eye, as at g, iig. 1, car; ried outtherefrom, to lead the chain from the roller-pin e, as before explained.Sometimes I tit a whelped bo`ss on the pin e for the chain d to passround. v

The arrangements before described are equally applicable to maps andother articles mounted upon rollers.- In applying them to Venetianblinds, I employ above the blind a roller round the pin, on the en d ofwhich the chain passes, as in tig. 1. The ordinary cords which passthrough apertures in the laths arc connected' to this roller, so thatwhen the chain is pulled, and the roller thereby caused to revolve,the-cords wind round the roller, thus raisingthe blind. When the chainis allowed to run, the weight of the blind causes the cords te unwindfromvthe roller while the blindiis lowered.

The arrangements can also be applied to carriage-windows and otherframes and outside blinds, by'securing the upper end of the chain to thetop of the window or other part to be raised or lowered, carrying itovera pulley above and over a second pulley at the sidc, about parallelYwith the first pulley, and finally carrying it down to the apparatusbefore explained. This arrangement is represented in'Figure 8, Where thechain d is shown attached at one end to the top of a carriage-Window,then carried over two pulleys 'r s, and finally carried down to one ofthe catches or holding apparatus. p

the modications described the same features exist, namely, a slit tocatch the links of tho chain, and a guide or pulley so situated inrelation to the chain and slit that it causes the chain to fall by itsown gravity into the slit when the chain is let go suddenly.

What I-claim as my invention, and desire to secure by Letters Patent,isf- 1. The combination of the slit, guide, and chain, arranged withreference to each other and a Windowblind, curtain, &c., so as tooperate substantially in the manner set forth, the combination beingsubstantially,1 such as described.

2. I claim the combination of the slit, guide, and chain with the lever,which, when lifted, moves the chain out of the slit, the combinationbeing 4substantially such as herein set forth.

GEORGE AILIX.
